This is not good advice. Once you threaten to sue, most Big Companies will stop talking to you via customer support channels and make you do everything in writing to their legal department.
Don't do this.

That would be fine. When I have threatened to sue someone and got no response, I will do the small claim as next step. One threat, one opportunity to resolve. More talking would enable more delays. No more communication from me aside from in writing from the court.
Generally gets a panicked phone response at speed and offering full settlement. I've had several expansive apology letters. A couple ignored the summons and waited for the default judgement before it got settled. Those were big, very well known companies, which could be pure coincidence. Most have asked "why did you sue?". Waiting for months to get that promised refund, whilst only getting excuses or lies, maybe? :)
Also I don’t tell the company I’m suing them. They could care less about me. I am however telling them THE STATE will be looking into their practices, which to them is much scarier and expensive than a disgruntled customer.
